About EDF Energy and Utility Warehouse
Who is EDF Energy?
EDF Energy is one of the UK's largest domestic energy suppliers and the UK branch of the French state-owned energy group, Électricité de France. It entered the UK market in 2003. The supplier offers standard variable, fixed, and tracker tariffs, but its focus on electric vehicle tariffs and smart home technology sets it apart. It installs smart meters, solar panels, and air source heat pumps, and uses its own low-carbon generation to back its specialist tariffs.
Who are Utility Warehouse?
Utility Warehouse is one of the UK's biggest domestic energy suppliers and is owned by Telecom Plus PLC. It grows through a word-of-mouth model using independent partners to sign up new customers. The key difference is its multi-service model, which lets customers bundle energy with broadband, mobile, and home insurance into one monthly bill. Customers get cheaper energy rates and a cashback card when they take multiple services.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
